When clients communicate with \s-1XPA\s0 access points, +they specify which access points to communicate with using +an identifier of the form: +.PP +.Vb 1 +\& class:name +.Ve +.PP +All registered \s-1XPA\s0 access points that match the specified identifier +will be available for communication (subject to access control rules, +etc.) +.PP +As of \s-1XPA\s0 2.1.5, the length of both the class and name designations are +limited to 1024 characters. +.PP +The \s-1XPA\s0 class:name identifier actually is a template: it accepts wild +cards in its syntax, so a single specifier can match more than one \s-1XPA\s0 +access point. (Note that the class is optional and defaults to \*(L"*\*(R".) +The allowed syntax for clients to specify the class:name template is +of the form shown below. (Note that \*(L"*\*(R" is used to denote a generic +wild card, but other wild cards characters are supported, as described +below). +.PP +.Vb 7 +\& template explanation +\& \-\-\-\-\-\-\-\- \-\-\-\-\-\-\-\-\-\-\- +\& class:name exact match of class and name +\& name match any class with this name +\& *:name match any class with this name +\& class:* match any name of this class +\& *:* match any access point +.Ve +.PP +In general, the following wild-cards can be applied to class and name: +.PP +.Vb 5 +\& wildcard explanation +\& \-\-\-\-\-\-\-\- \-\-\-\-\-\-\-\-\-\-\- +\& ? match any character, but there must be one +\& * match anything, or nothing +\& [...] match an inclusive set +.Ve +.PP +Although the class:name template normally is used to refer to \s-1XPA\s0 +access points, these also can be specified using their individual +socket identifiers. For inet sockets, the socket identifier is +\&\fBip:port\fR, where ip can be the DNS-registered name, +the \s-1ASCII\s0 \s-1IP\s0 number (e.g. 123.45.67.890) or the hex \s-1IP\s0 number +(e.g. 838f3a60). For unix sockets, the identifier is the socket file +name. These socket identifiers are displayed as the fourth argument +in the xpans display of registered access points. For example, +consider the ds9 program started using inet sockets. The xpans name +server will register something like this: +.PP +.Vb 2 +\& csh> xpaget xpans +\& DS9 ds9 gs saord.harvard.edu:3236 eric +.Ve +.PP +You can access ds9 using ip:3236 in any of the three forms: +.PP +.Vb 2 +\& csh> xpaget saord:3236 file +\& /home/eric/data/snr.ev +\& +\& csh> xpaget 123.45.67.890:3236 file +\& /home/eric/data/snr.ev +\& +\& csh> xpaget 838f3a60:3236 file +\& /home/eric/data/snr.ev +.Ve +.PP +In the case of unix sockets, the socket identifier is a file: +.PP +.Vb 2 +\& csh> xpaget xpans +\& DS9 ds9 gs /tmp/.xpa/DS9_ds9.2631 eric +\& +\& csh> xpaget /tmp/.xpa/DS9_ds9.2631 file +\& /home/eric/data/snr.ev +.Ve +.PP +This feature can be useful in distinguishing between multiple +instances of a program that all have the same class:name designation. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +See xpa(n) for a list of \s-1XPA\s0 help pages |
